Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 60

To establish multiple PPP point-to-point connections in the Ethernet network, a PPPoE server establishes connections with multiple PPPoE clients on one
Ethernet port.
How does PPPoE differentiate between each connection?

Answer options

• A. MAC address.
• B. IP address and MAC address
• C. MAC address and ppp-id
• D. MAC address and session-id

Correct answer: D

Explanation

The correct answer is D, as PPPoE uses a session-id to uniquely identify each connection along with the MAC address. Options A, B, and C do not provide the necessary unique identification for multiple connections, as they either lack the session-id or include combinations that do not resolve the differentiation needed.
